In chapter 17 Boruto mentions the field trip to the Land of the Mist that we see in the anime. So are they trying to incorporate the filler into the canon now? But then where is all the anime original students?
Half and half. Mostly filler tho.
Only part I consider filler is what Bolt did. He has only enough chakra o make 4 clones. So his chakra is divided by 4 each time 1 is destroyed that chakra disappears for good. So Boruto with a quarter stamina shouldn't have been able to make shadow clones and spam jutsu like he did. That sort of took away from his character and made it an arsepull 2.0
Idk why or how supposedly dude somehow have hella chakra in the anime and can spam 4 kage bunshins and other techniques with no fatigue when his reserve's are lower than Sarada's who was tired from Sharingan and 1 kage bunshin.
Also the raiga part is filler. Naruto only killed him in filler and dude was young af yet in the manga he was Might Dai age or a bit younger and was stated(?) Dai killed 3/4 out of the 7 and we know of 2 or 3 that survived in canon to become part of the 2nd generation swordsman.
Pretty much agree on Boruto. However there 're some fans trying to dismiss canon stats because Boruto's performing arsepull after arsepull.
Thee raiga is filler in the Naruto manga/anime they've made Raiga canon for the Boruto series. We have to keep in mind that the two aren't the same thing or by the same author. So something can be canon in Boruto even of its filler on Naruto.
The trip was canon, what went on is not.
